639561 ÷ 67 
We want to figure out the number of times 639561 can be divided by 67.

Let's proceed to step 1:
If we divide 6 by 67, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 67

Advancing to step 2:
67 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 67

Going ahead to step 3:
67 can be fit into 639 9 times, resulting in a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 603 away from 639, we end up with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 67

Moving on to step 4:
The number 67 fits into 365 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 95.0
If we take 335 away from 365, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 67

Advancing to step 5:
67 goes into 306 4 times with a remainder of 38.
The next digit of our result is 4. 
Result so far: 954.0
Subtracting 268 from 306 leaves us with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 67

Going ahead to step 6:
67 goes into 381 5 times with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 9545.0
Subtracting 335 from 381 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
67 goes into 460 6 times with a remainder of 58.
The next digit of our result is 6. 
Result so far: 9545.6
Subtract 402 from 460 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
When dividing 580 by 67, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 9545.68
If we subtract 536 from 580, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 67, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 9545.686
Deduct 402 from 440 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
The number 67 fits into 380 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 9545.6865
Deduct 335 from 380 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
If we divide 450 by 67, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 9545.68656
Deduct 402 from 450 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
480 divided by 67 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 9545.686567
If we take 469 away from 480, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
67 goes into 110 1 times with a remainder of 43.
The next digit of our result is 1. 
Result so far: 9545.6865671
If we subtract 67 from 110, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
When dividing 430 by 67, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 9545.68656716
Deduct 402 from 430 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 9545.68656716, and the remainder is 2.8e-08.
